Joshua was taking a trip to an amusement park with his family. to get his family in, his parents had to purchase two adult tickets, one child ticket, and one toddler ticket. the cost of an adult ticket was $45.50. a child ticket was 8/10 of the price of an adult ticket, and a toddler ticket was 2/5 of the price of an adult ticket. how much was the child ticket?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

b.-4 units

all you   do is count how many times you move
